Here how the inside is made. I used combination of 5/8 MDF on the outside and 3/4 maple plank (3" wide) used for flooring on the inside. I wanted to combine both materials as MDF is pretty stable and good for laminating, while maple I hoped would add some properties to the better sound. Front baffle is also hardwood and I used here a cut-off from Ikea tabletop. I didn't want to use MDF as I used screws to hold the side panels and MDF is not really strong enough for that. To set the shape of the inside channels, I used 1/4 MDF side panels and that helped me in assembling everything that is seen in this pic.

For the sides I chose 1" x 6" maple boards and they are glued to the 1/4 sub panels. I also had to use screws to both simplify construction and prevent maple boards fram warping. I used filler to cover the holes and biscuit foints to strengthen everything. The corners are rounded on a router with 3/4" radius bit and everything is sanded with 220 grid paper and later sealed with Thompson Water Seal used for decks. It gives very smooth and natural looking finish, which I personally think is nicer than using laquer. The listening tests are still to follow. I still have some doubts as to how much damping should I use and if to cover all sides with foam on the inside or not. Just to add extra rigidity I attached 6" x 6" copper plates to the side panels, where the woofer is mounted.

I used some blown rubber around tweeter. First it improves the sound of high frequencies, second it gives better look, as I had impression that visually the tweeter was too low. It's better balanced now

So are you going with active or passive crossovers, or don't you know yet?

Looking at that response graph, it seems like you have a good little driver, little evidence of cone breakup modes at any rate.

Looking at the roll off though, it looks like it might be a bit steep to integrate well with a first order on the tweeter, you might need to go second, or even third to sum flat.

Second order is what I actually had in mind as the similar aproach was used in a Titus (or Titan maybe), a small Triangle monitor. No crossover on midbass and secon order filter on the same tweeter I'm using here. Sam Telling, of Stereophile, was raving about imaging properties of that small Triangle monitor and I also built it few years ago.

Originally posted by JasonL I would say some thing but i email you for questions now and never get a responce. So yeah. !

Obviously, I must have been busy building those speakers. I have to find info on those Freds.
